Purchase now: Winner ES-08W-2H-15-Z-04 Spool Valve
Purchase now: Atlantech Drives provides you the Winner Hydraulics ES-08W-2H-15-Z-04. This is a specialized Normally Open (NO) Solenoid Spool Valve («2H» code) designed for safety-critical or unloading circuits. It fits the standard Size 08 cavity. Crucially, this model is equipped with a DIN 43650 Connector coil («15» code), also known as ISO 4400 or Hirschmann style. This is a significant upgrade over lead wires, offering superior water and dust protection (IP65/IP67) when mated with a gasketed plug.
Technical Specifications and Connector Benefits
The Normally Open logic means the valve allows flow from Port 1 to 2 freely when there is no power. When you apply 12V DC («04»), the spool shifts to block the flow. This logic is essential for «Fail-Safe Open» applications—for example, ensuring a cooling fan turns on (valve opens to flow) if the control signal wire is cut. The DIN connector allows for a detachable cable, making future coil replacements «plug-and-play» without cutting or soldering wires.

Expert Installation Advice: Wiring the DIN Plug
Don’t ignore the gasket. Expert Tip: When installing the mating plug for the DIN 43650 connector, ensure the small rubber gasket is present between the plug and the coil face. Without it, water will wick into the terminals, causing corrosion and eventually a short circuit, blowing the fuse on your 12V source. Also, standard DIN plugs allow you to orient the cable exit in 90-degree increments—rotate it so the cable hangs downwards to create a «drip loop.»
Frequently Asked Questions (FAQs)
Q: Can I replace a «14» (Wire) model with this «15» (DIN) model?
A: Yes, the hydraulic cartridge is identical. However, you will need to crimp a DIN connector onto your machine’s wiring harness to plug it in.
Q: Does Normally Open mean it drains the battery?
A: It depends on your circuit. If the «normal» state of your machine requires the valve to be closed, you must keep it energized, which consumes power (battery). Design your circuit so the solenoid is off for the majority of the time.
